WLS Codebooks

Note: Codebooks contain frequency data from the private data release. For some variables, these differ from the frequencies in the public release. Variables that differ between the public and private versions include "(not available on public release)" as part of the variable description, or a note indicating the difference between the public and private versions.

OVERVIEW

The 2011 round of WLS data collection is the first to include items
ascertaining risk aversion and willingness to delay gratification, what is
known as impulse control. Risk aversion is measured using hypothetical
scenarios involving the potential for gaining versus losing money. Each
question asks the participant to indicate which of two possible hypothetical
scenarios - both carrying different probabilities for gaining or
losing/maintaining various amounts of money - they would prefer. Impulse
control is measured using hypothetical scenarios about gaining a particular sum
of money at one point in time versus gaining a larger sum of money later on.
With the duration of the wait and amount of extra money yielded by it varying
across hypothetical scenarios, each question asks the participant to indicate
which of two possibilities they would prefer. 

While the majority of participants did not receive any financial compensation
for completing this section, a computer randomly selected and decided the
outcome of one of the risk aversion questions (PSTK02RE-PSTK22RE) for a small
random sub-sample. Members of the sub-sample were financially compensated in a
manner consistent with their response to the randomly selected question.

Note: A small sub-sample of participants were randomly selected to be financially compensated for completing the Real Stakes Module. For such participants, one scenario from the risk aversion questions that did not include a possibility of financial loss (PSTK02RE-PSTK22RE) was randomly selected for realistic use. Participants were then compensated based on their answer to the selected question and the probabilities contained therein.
Note: A value of "1" denotes selection for the "real stakes" condition, whereas a value of "0" denotes participation in the purely hypothetical condition.
Note: The risk aversion questions used to determine financial compensation (PSTK02RE-PSTK22RE) were prefaced by the following set of instructions: "The next section presents several scenarios. After you return this completed questionnaire, a computer will randomly choose and determine the outcome of one of the scenarios. You will be mailed a check in the dollar amount corresponding to your choice on that question. If you select Choice A, you would have a 100% chance of getting a certain amount. If you select Choice B, you would have a 50% chance of getting the dollar amount specified and a 50% chance of getting $0. There are no right or wrong choices, since we are simply measuring your personal preferences."

Note: A small sub-sample of participants were randomly selected to be financially compensated for completing the Real Stakes Module. For such participants, one scenario from the risk aversion questions that did not include a possibility of financial loss (PSTK02RE-PSTK22RE) was randomly selected for realistic use. Participants were then compensated based on their answer to the selected question and the probabilities contained therein.
Note: See PSTK01RE for information on the number of participants selected for the "real stakes" versus purely hypothetical conditions of this Module, as well as the exact instructions provided to participants selected for "real stakes" compensation.
Note: This variable indicates which of the risk aversion items that did not include a possibility of financial loss (PSTK02RE-PSTK22RE) was randomly selected to determine compensation for participants belonging to the "real stakes" condition. The values range from 2 to 22 and reference the scenarios that could have been selected. Therefore, a value of "4" would indicate that variable PSTK04RE was selected to determine compensation, while a value of "17" would indicate that variable PSTK17RE was selected.

pstk24re: Dollar amount of financial compensation paid to Participants in the 'real stakes' sub-sample.
